Columbia Sportswear spent $80,000 Friday to send a cheeky message to Congress and President Donald Trump: Fund the government and particularly the national parks.

In a thinly veiled send-up of President Donald Trump’s campaign slogan, the Portland company urged “Make America’s Parks Open Again” with a full-page ad in Friday’s Washington Post.

The ad contained a personal plea from Tim Boyle, Columbia’s chief executive officer and chairman: “Walls shouldn’t block access to parks, and federal workers shouldn’t be left out in the cold. Work together to open our parks.”

The ad was published on day 21 of the federal shutdown, which has idled hundreds of thousands of workers and forced thousands of others to work without pay. The shutdown has meant park rangers and other administrative and security staff at the country’s 58 national parks are off the job. That has led to a disgusting mess at some parks, where janitors aren’t around to clean the restrooms and many restrooms are locked.

On Jan. 3, National Parks employees closed the last four miles of the road to Crater Lake, saying that the government shutdown and a lack of proper ‘leave no trace’ etiquette had resulted in a build-up of human waste. Crater Lake is Oregon’s only national park.

Boyle said the shutdown of the parks has a real impact on Columbia Sportswear, which sells a wide variety of apparel and footwear for use in the outdoors. “Clearly, the outdoors is a huge part of our business,” he said. “Parks in the U.S. are where people use our products. Parks are being damaged by people doing things they probably wouldn’t do if management were in place.”

This is not the first time Boyle has criticized the Trump administration. When Trump first threatened a trade war with China, Boyle decried what he called “amateur hour” in the White House.

But if publicly calling out Trump and Congress does anything to change the tenor of the current political debate, Boyle said he would consider it money well spent. “It has to be said, the current situation is insane," Boyle said. “This is very dangerous time for our country.”
